Organic Mulche for Weed Managing with Application of Spent Edible Mushroom
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 11
Abstract
There is a growing concern and demand for healthy food on behalf of both policy makers and the public. Traditional saffron production systems which, in both technical and social terms are forms of ecological production are still operated in many parts of Iran. A return to more sustainable production systems in a country like Iran with a long history of ecological agriculture could be one effective method to protect the fragile local environments. Agronomic practices such as application of organic fertilizers, nonchemical methods for pests and weed control, complete family labour work for production and processing, share-cropping and socio-cultural environment surrounding the whole process of saffron is in compliance with organic farming principles. Alternative treatments in which application of chemical pesticides is at its lowest level have been under increasing consideration. There are various references showing that application of bottom mushroom bed residue compost bring different benefits such as weed reduction, water capacity and soil structure improvements. In order to study the effect of application rate of mushroom bed residue compost on density and biomass of weeds in saffron, a field experiment based on a randomized block design with four replications is under study in the research field unit of Ferdowsi University of Mashhad. Treatments included 0, 15, 30, 45 and 60 t/ha of the compost. Results of first sampling showed a significant effect of compost on weed population and density. Maximum weed control was observed with application of 45 t/ha, however, detailed results of the present study will be available after taking second weed sample and comparing next year saffron yield.
